A honey bee makes 103 pounds of honey in one month. Another honey bee can make 179 pounds of honey in one month. Choose all of the equations that show a reasonable estimate for how much honey they make together.
105 + 180 = 285
100 + 50 = 150
100 + 180 = 280
100 + 200 = 200
120 + 150 = 270

about 200
about 300
about 400
about 500
Choose the equation that is true
80 + 130 = 130 + 80
0 + 110 = 0
45 + (89 + 25) = 89 + 70
(89 + 10) + 27 = 90 + (10 + 27)
Choose the equation that is true
78 + 80 = 80 + 80
90 + 0 = 0
0 + 78 = 78
(114 + 10) + 60 = 114 + (20 + 60)

Miss Cardoso subtracts 328 from 782 and gets 454. What addition equation can he use to check his answer?
782 - 328 = 454
454 + 328 = 782
454 + 782 = 1,236
500 + 330 = 830
Megan earned $225 dog walking in September. In October she earned $103. She wants to estimate how much more she earned in September than in October.
Which compatible numbers could she subtract to get a reasonable estimate?
$300 - $100 = $200
$230 - $100 = $130
$200 - $150 = $50
$200 - $50 = $150

Third grade raised $178 for their field trip. Fourth grade raised $105 for their field trip.
Dr. Maroun wants to estimate how much more 3rd grade raised than 4th grade.
Round the numbers to the nearest ten to solve.
$200 - $100 = $100
$180 - $110 = $70
$180 - $105 = $75
$175 - $105 = $70
